In economics, protectionism is the economic policy of restraining trade between states (countries) through methods such as tariffs on imported goods, restrictive quotas, and a variety of other government regulations designed to allow (according to proponents) fair competition between imports and goods and services produced domestically. According to their proponents, protectionist policies protect the businesses and workers within a country by restricting or regulating trade with foreign nations. In recent years, protectionism has manifested itself through popular anti-globalization and anti-immigration movements. The doctrine of protectionism contrasts with the doctrine of free trade, where governments reduce as much as possible the barriers to trade. There is a broad consensus among economists that the impact of protectionism on economic growth (and on economic welfare in general) is largely negative,〔See P.Krugman, «The Narrow and Broad Arguments for Free Trade», American Economic Review, Papers and Proceedings, 83(3), 1993 ; and P.Krugman, Peddling Prosperity: Economic Sense and Nonsense in the Age of Diminished Expectations, New York, W.W. Norton & Company, 1994.〕 although researchers have pointed out that the magnitude of this impact varies considerably across countries and crucially depends on the macroeconomic and policy environment. ==Protectionist policies== A variety of policies have been used to achieve protectionist goals. These include: * ''Tariffs'': Typically, tariffs (or taxes) are imposed on imported goods. Tariff rates usually vary according to the type of goods imported. Import tariffs will increase the cost to importers, and increase the price of imported goods in the local markets, thus lowering the quantity of goods imported, to favour local producers. Tariffs may also be imposed on exports, and in an economy with floating exchange rates, export tariffs have similar effects as import tariffs. However, since export tariffs are often perceived as 'hurting' local industries, while import tariffs are perceived as 'helping' local industries, export tariffs are seldom implemented. * ''Import quotas'': To reduce the quantity and therefore increase the market price of imported goods. The economic effects of an import quota is similar to that of a tariff, except that the tax revenue gain from a tariff will instead be distributed to those who receive import licenses. Economists often suggest that import licenses be auctioned to the highest bidder, or that import quotas be replaced by an equivalent tariff. * ''Administrative barriers'': Countries are sometimes accused of using their various administrative rules (e.g. regarding food safety, environmental standards, electrical safety, etc.) as a way to introduce barriers to imports. * ''Anti-dumping legislation'': Supporters of anti-dumping laws argue that they prevent "dumping" of cheaper foreign goods that would cause local firms to close down. However, in practice, anti-dumping laws are usually used to impose trade tariffs on foreign exporters. * ''Direct subsidies'': Government subsidies (in the form of lump-sum payments or cheap loans) are sometimes given to local firms that cannot compete well against imports. These subsidies are purported to "protect" local jobs, and to help local firms adjust to the world markets. * ''Export subsidies'': Export subsidies are often used by governments to increase exports. Export subsidies have the opposite effect of export tariffs because exporters get payment, which is a percentage or proportion of the value of exported. Export subsidies increase the amount of trade, and in a country with floating exchange rates, have effects similar to import subsidies. * Exchange rate manipulation: A government may intervene in the foreign exchange market to lower the value of its currency by selling its currency in the foreign exchange market. Doing so will raise the cost of imports and lower the cost of exports, leading to an improvement in its trade balance. However, such a policy is . * International patent systems: There is an argument for viewing national patent systems as a cloak for protectionist trade policies at a national level. Two strands of this argument exist: one when patents held by one country form part of a system of exploitable relative advantage in trade negotiations against another, and a second where adhering to a worldwide system of patents confers "good citizenship" status despite 'de facto protectionism'. Peter Drahos explains that "States realized that patent systems could be used to cloak protectionist strategies. There were also reputational advantages for states to be seen to be sticking to intellectual property systems. One could attend the various revisions of the Paris and Berne conventions, participate in the cosmopolitan moral dialogue about the need to protect the fruits of authorial labor and inventive genius...knowing all the while that one's domestic intellectual property system was a handy protectionist weapon." * Employment-based immigration restrictions, such as labor certification requirements or numerical caps on work visas. * Political campaigns advocating domestic consumption (e.g. the "Buy American" campaign in the United States, which could be seen as an extra-legal promotion of protectionism.) * Preferential governmental spending, such as the Buy American Act, federal legislation which called upon the United States government to prefer U.S.-made products in its purchases. In the modern trade arena many other initiatives besides tariffs have been called protectionist. For example, some commentators, such as Jagdish Bhagwati, see developed countries efforts in imposing their own labor or environmental standards as protectionism. Also, the imposition of restrictive certification procedures on imports are seen in this light. Further, others point out that free trade agreements often have protectionist provisions such as intellectual property, copyright, and patent restrictions that benefit large corporations. These provisions restrict trade in music, movies, pharmaceuticals, software, and other manufactured items to high cost producers with quotas from low cost producers set to zero.〔() 〕〔(The Conservative Nanny State )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「protectionism」の詳細全文を読む スポンサード リンク
